摘要： Apparatus for sealing the primary-side coolant flow nozzles of a nuclear steam generator. The steam generator has relatively small diameter manway openings for providing access to the interior of the steam generator including the inside surface of each nozzle, the manway openings having a diameter substantially less than the inside diameter of each nozzle. The apparatus includes a bracket having an outside surface for matingly sealingly engaging the inside surface of the nozzle. The bracket also has a plurality of openings longitudinally therethrough and a plurality of slots transversely therein in communication with each opening. A plurality of unitary plugs sized to pass through the manway opening are matingly sealingly disposed in each opening of the bracket for sealingly plugging each opening. Each plug includes a plurality of arms operable to engage the slots of the bracket for connecting each plug to the bracket, so that the nozzle is sealed as the plugs seal the openings and are connected to the bracket.

摘要： An in-line, multi-stage pump powered by integral canned electric motors. At least two pump units are connected in series in a pipeline. Each of said pump units includes a hollow housing having a hermetically sealed stator mounted therein. The stator is electrically connected to a source of electrical energy. An impeller assembly that includes a tubular suction shroud and impeller is rotatably mounted inside the housing. The impeller assembly includes a hermetically sealed rotor which is mounted around the suction shroud and positioned inside the stator in operative association therewith. Energizing the stator rotates the rotor, which in turn rotates the impeller to pump fluid from the intake end of the housing to the outlet end of the housing. The subsequent pump units add pressure and/or maintains the pressure of the pumped fluid.

摘要： A passively temperature actuated valve has a shape memory alloy (SMA) mechanism connected to a lever arm which engages the valve stem to actuate the valve against the biasing force of a valve stem biasing spring when the ambient temperature rises above the transition temperature of the SMA. The SMA mechanism can include an SMA rod, but preferably has a tube of shape memory alloy supported in couplings which allow ambient fluid to freely pass through the tube. A stack of Bellville springs concentrically mounted over the tube biases the tribe to the elongated condition when below the transition temperature. An optional latch latches the valve in the actuated position if it is required that the valve remain actuated when the ambient temperature falls below the transition temperature and the Bellville springs again elongate the SMA member.

摘要： A fluid pump powered by an integral canned motor includes a housing having a cylindrical passage extending therethrough. A sealed annular stator is mounted around the housing. An impeller assembly is rotatably mounted in the passage in the housing. The impeller assembly includes an axial flow impeller and a sealed rotor mounted around the periphery of the impeller. Bearings, including thrust bearings, are mounted between the periphery of the impeller assembly and the housing. A radial flow auxiliary impeller may be mounted on the impeller assembly to create a radial flow of water from the cylindrical passage in the housing to a peripheral fluid circulation channel between the impeller assembly and the housing. The auxiliary flow impeller pressurizes the peripheral fluid circulation channel.

摘要： A two-stage submersible propulsor unit comprises a shroud having a water inlet and a water outlet, a shaft assembly centrally mounted within the shroud, an upstream and a downstream propeller, each of which includes a separate hub rotatably mounted on the shaft assembly, first and second electric motors separately rotating the upstream and the downstream propellers. Each motor includes a rotor mounted around the outer periphery of one of the propellers and a stator mounted around the shroud, and first and second thrust bearing assemblies for absorbing the thrust load generated between the hubs of the first and second propellers and the shaft assembly. Both thrust bearing assemblies are contained within a housing located on the downstream end of the shaft assembly. The shaft assembly includes a stationary outer shaft where the first and the second propellers are rotatably mounted, and a rotatable inner shaft which is connected to the hub of the upstream propeller for transferring thrust from the upstream propeller to the first thrust bearing assembly located in the downstream end of the shaft assembly. The foregoing arrangement advantageously avoids positioning a thrust bearing assembly in front of the upstream propeller which in turn would interfere with the smooth flow of water into the unit, and create noise.

摘要： A pressurized water reactor of an advanced design comprises, in vertically spaced relationship, a lower barrel assembly having lower and upper core plates, an inner barrel assembly and an axially removable calandria assembly having a lower calandria plate. A plurality of rod guides are cantilever-mounted in parallel axial relationship within the inner barrel assembly by rigidly mounting the lower ends thereof to the upper core plate. Axially extending sleeves affixed to the upper ends of the rod guides and telescopingly receive therein generally cylindrical supports which are affixed to and depend downwardly from the lower calandria plate and define alignment axes for the respectively associated rod guides. Axially extending leaf springs in each sleeve are normally biased radially inwardly and, in the assembled relationship of the calandria and inner barrel assemblies, resiliently and frictionally engage the respective cylindrical supports to maintain alignment and react both lateral and axial loads. Load pick-up surfaces of non-yielding sleeve portions react excessive loads directly into the lower calandria plate. Mating top end supports for RCC and WDRC rod guides permit dense packing of same, while internal openings of the top end supports permit telescoping movement of the corresponding rod clusters therethrough to permit ease of assembly and disassembly operations.

摘要： Cracks in the shaft of a reactor coolant pump adjacent a tapered end on which the impeller is mounted are removed by machining a circumferential groove in the pump shaft to a depth and an axial length which removes the cracks but does not extend into the tapered end of the pump shaft. A split ring fills the groove to an outer diameter which matches the outer diameter of the pump shaft. A thermal sleeve shrink fit over the split ring has internal annular ribs engaging the shaft and the ring to form an annulus which communicates with the pump chamber sufficiently to maintain a layer of substantially stagnant coolant over the split ring and the pump shaft at the pressure of the coolant being pumped. An oversized washer between the impeller and the impeller retainer nut overlaps the interface between the impeller and the tapered end of the pump shaft to impede the flow of hot reactor coolant along the keyways in the tapered end of the shaft and the impeller to minimize temperature fluctuations in the vicinity of the thermal sleeve. Preferably, the thermal sleeve has a lower coefficient of thermal expansion than those of the shaft and the split ring.

摘要： A hydro-ball in-core instrumentation system employs detector strings each comprising a wire having radiation sensitive balls affixed diametrically at spaced positions therealong and opposite tip ends of which are transportable by fluid drag through interior passageways. In the passageways primary coolant is caused to flow selectively in first and second opposite directions for transporting the detector strings from stored positions in an exterior chamber to inserted positions within the instrumentation thimbles of the fuel rod assemblies of a pressure vessel, and for return. The coolant pressure within the detector passageways is the same as that within the vessel; face contact, disconnectable joints between sections of the interior passageways within the vessel facilitate assembly and disassembly of the vessel for refueling and routine maintenance operations. The detector strings may pass through a very short bend radius thereby minimizing space requirements for the connections of the instrumentation system to the vessel and concomitantly the vessel containment structure. Improved radiation mapping and a significant reduction in potential exposure of personnel to radiation are provided. Both top head and bottom head penetration embodiments are disclosed.
